Solving COMSOL Error 7147 with Heat Transfer & RAM

[rr00053]

Hi everyone,
I am doing a simulation using COMSOL 3.3a... I am using heat transfer module. I have 3 subdomains in my design with sizes in range mm, micrometre and nanometer...the third nanometre block appears just as a line...bt however i was able to give all boundary and subdomain details as i wanted...i did meshing and wen i proceeded with solving it says...
error 7147: out of memory in time dependent solver.

how can i get through with this error...please help me...

Thanks in advance.

When running on my PC that usually means that I ran out of RAM. The solution: decrease your mesh size or buy more RAM.
